Title: Method for forming filter material bed in filter machine
Inventor: MIYATA TOSHIO
IPC: B01D37/02
Filed: 1985-04-16
Abstract: PURPOSE:To obtain a filter capable of fine dust from the beginning, by allowing a liquid in which a fibrous material such as paper was dispersed and a liquid having a powdery material dispersed therein to successively transmit through a filter. CONSTITUTION:Paper is supplied to a supply cylinder 26, into which a liquid was preliminarily supplied, to be dispersed in said liquid. The resulting dispersion is flowed out from a supply port 19 to the peripheral direction and flowed into a main tank chamber 12 as a vortex stream from the opening provided to the lower end of a partition wall 9. A considerable amount of a fiber is adhered to the outer peripheral surface of a filter 11 and the dispersion is discharged from an outflow port 16 to be recirculated. The formed fiber bed reaches a thickness of about 10mm. Next, a powdery material is supplied to the supply cylinder 26 from the opening thereof to be dispersed in the liquid and the resulting dispersion is transmitted through the filter 11 to be recirculated. By this method, the powdery bed is adhered to the peripheral surface of the aforementioned fiber bed and the filter bed is compressed by the sucking action in the filter by a pump 22. The thickness of the filter material bed is about 3mm.

Title: Color original document reader
Inventor: NAGASAWA KIYOTO
IPC: H04N1/04
Filed: 1986-04-10
Abstract: PURPOSE:To prevent the deterioration in the quality of a read picture by arranging a mark corresponding to a read start position of an original document at the outside of reading in the main scanning direction for an original picture and setting the star timing in the effective picture range in the subscanning direction based on the detection timing of the said mark. CONSTITUTION: In reading a picture of the original, when a line image sensor 8 reads a white picture WS of a width (a), a sample-and-hold circuit 24 is oeprated to sample the picture signal level corresponding to the white level at that time. Then the gain of the analog processing section 20 as a white balance level is set when the line image sensor 8 reads the picture of the original on a contact glass 1 as to the said line. Thus, the effect of the luminous quanity fluctuation of the light source 2 at the subscanning movement and the effect of the difference from the transmittivity of a color separation filter 6 are eliminated.

Abstract: PURPOSE:To increase the degree of integration and to prevent a surface breakdown between the emitter and base of a bipolar TR by forming a Zener diode structure between the 1st conduction type emitter area and the 2nd conduction type base area of the TR. CONSTITUTION:An epitaxial growth layer 3 is formed on a semiconductor substrate 1 and an island 10 is formed of an insulating layer 4. An N<+> layer 8 as a collector C and a P layer 5 as a base B are formed in the island 10 and an N<+> layer 7 as an emitter E is formed in a base B by impurity diffusion. Further, a P<+> layer 6 is formed at part of the P layer 5 in contact with at least the bottom surface part of the N<+> layer 7. In this case, the diameter B of the P<+> layer is less than the diameter A of the N<+> layer. Therefore, an area with higher dielectric strength than an original TR is formed at the contacting part between the P<+> layer 6 and emitter layer 7, so a breakdown occurs to not the surface, but this contacting part.

CONSTITUTION:The outputs obtained by multiplying a reference signals SF and SF' having a 90 deg.  phase difference and a measurement output signal SO together respectively are inputted through  LPFs LP1 and LP2 to a calculating circuit LS to obtain the sum of the squares of the two input  signals and the square root thereof, and the conversion coefficient N of a frequency converting  circuit FT which frequency-converts a measurement input signal SM and generates a reference  signal is selected to be 1- integer multiple. In other words, once the conversion coefficient N is determined, if the measured frequency changes, the frequencies of the reference signals SF  and SF' change in proportion thereto. Therefore, any one of the frequency component signals  included in the measurement output signal SO can be detected by means of a single filter circuit.  By such a constititon, it is possible to detect both the fundamental wave and the higher harmonic  component included in the measured signal with a single filter circuit.

Title: Controller for fluid temperature
Inventor: SATONO TADASHI
IPC: G05D11/16
Filed: 1985-04-19
Abstract: PURPOSE:To prevent the abnormal overheat of a heater by using a flow rate lower limit actuator to stop the actuation of the heater when the feed amount of the fluid is less than the prescribed level to the heater. CONSTITUTION:A flow rate lower limit actuator 3 breaks a power supply 4 when the amount of the fluid supplied to a heater 6 is less than the prescribed level and stops the actuation of the heater 6. In this example the amount of the fluid supplied to the heater 6 is obtained indirectly from the control signal of a program temperature controller 1. In other words, the actuator 3 compares the lower limit amount of the fluid set previously with the amount of the fluid obtained from said control signal and supplied to the heater 6. Then the actuator 3 breaks the power supply 4 when the amount of the fluid supplied to the heater 6 is less than the lower limit amount of the fluid and then controls a control valve 5 for change of the output ratio between the amount of the fluid supplied to the heater 6 and that supplied to a cooler 7. This prevents the abnormal overheat owing to the reduction of the amount of the fluid supplied to the heater 6.
